Application August 15, 1950, Serial No. 179,606 6 Claims. (01. 3.0-6.1)

I The present invention relates to new and useful improvements incanopeners-and more; particularly to a wall attached can punch for easilyand quickly punching a pair of openings in the top of a can.. r

An important object of, the invention is to provide a canv punch havinga can. holder connected to a wall attached bracket'by pivoted arms forvertical swinging movement of the can holder and connecting" theupper'end' of' the can holder to the bracket by means of a pivotedpressure arm having cutters at its outer end to penetrate the top of thecan as the can holder swings downwardly.

A further object of the invention is to provide a novel can punch orcutter construction carried by the pressure plate.

A still further object is to provide a device of this character ofsimple and practical construction, which is strong and durable,efi'icient and reliable in operation, realtively inexpensive tomanufacture and otherwise well adapted for the purposes for which thesame is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing the can holder in can punchingposition;

Figure 2 is a longitudinal sectional view show ing the can holder inraised position;

Figure 3 is a horizontal sectional view taken on a line 33 of Figure 2;and

Figure 4 is a fragmentary perspective view of the outer end of thepressure arm showing the cutters thereon.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,thenumeral 5 designates a wall bracket constructed of a metal platehaving forwardly projecting flanges 6 at its side edges.

A rod or pin 1 is supported at its ends in the lower portion of flanges6 and on which an arm 8 is pivoted by means of a forked inner end 9 onthe arm. The outer end of arm 8 is formed with an upstanding extensionIE to which a shelf portion l3 of a can holder 14 is pivoted by means ofan ear H at the underside of the shelf and a pin [2 connecting the earto extension.

The arm 8 and can holder H! are supported in a raised horizontalposition by means of a coil spring [5 connecting the outer portion ofarm 8 to the upper portion of bracket 5.

, arm. [1.

upper pin. isis supported in the upper portion of flanges 6 of bracket15and a pressure plate orarm: H has its inner ends welded or otherwiseconnected to pin it for vertical swinging. movement.

The upper'portion of can holder I4 is formed at its side portions withapair of upstanding: apertured ears I8: in which a rodor pin l9- ispivoted, the'rod or pin- 59 being weldedor otherwise suit ably securedto the outer end portion of pressure A pair of cutters 20 projectoutwardly in a downwardly curved position at the outer end of pressurearm I1, the cutters being formed as in tegral extensions on the pressurearm, and a brace 2| is welded on top of each cutter and bears againstthe rod I9. The outer end of the braces taper to match the tapered endsof the cutter.

In the operation of the device, spring l5 holds lower arm 8 and canholder l4 upwardly and the holder is swung downwardly by pressing on theouter edge of shelf l3. Pressure arm I! swings downwardly with holder Hito cause cutters 20 to penetrate the top of a can 22 supported on theholder.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A can punch comprising a wall bracket, up-

- per and lower arms pivoted at their inner ends to the bracket forvertical swinging movement, a can holder supported at the outer ends ofthe arms and pivoted thereto for maintaining a substantiallyperpendicular position during movement of the arms, and a pair ofcutters at the outer end of the upper arm for penetrating the top of acan supported on the holder.

2. A can punch comprising a wall bracket, upper and lower arms pivotedat their inner ends to the bracket for vertical swinging movement, a canholder supported at the outer ends of the arms and pivoted thereto formaintaining a substantially perpendicular position during movement ofthe arms, a pair of cutters at the outer end of the upper arm forpenetrating the top of a can supported on the holder, and spring meansholding the can holder and arms in a raised position.

3. In a can punch, the combination of a vertically swingable "canholderand a pressure plate connected to and swingable with the holder andhaving one end overlying a can supported on the holder, and a pair ofdownwardly curved cutters i.

carried by the pressure plate at its overlying end for penetrating thecan upon a downward move ment of the holder.

4. A can punch comprising a lower arm pivoted at one end to a supportingstructure for vertical swinging movement, an upper pressure plate alsopivoted at one end to the supporting structure above the lower arm, acan holder connected to the outer ends of the arm and pressure plate formovement therewith, and a pair of forwardly and downwardly curvedcutters integrally formed with pressure plate at its outer end forpenetrating a can held on the holder upon a downward movement thereof.

5. A can punch comprising a lower arm pivoted at one end to a supportingstructure for vertical swinging movement, a pressure plate also pivotedat one end to the supporting structure, a can holder pivoted at itsbottom to the outer end of the lower arm, a transverse rod fixed on topof the pressure plate at its outer end and projecting outwardly at theside edges of the pressure plate to form trunnions to which the top ofthe can holder is pivoted, and a pair of forwardly and downwardly curvedcutters integrally formed with the pressure plate at its outer end andover- Iying a can supported on the holder to penetrate the top of thecan upon a downward movement of the holder.

I 6. A can punch comprising a lower arm pivoted at one end to asupporting structure for vertical swinging movement, a pressure platealso pivoted at one end to the supporting structure, a can holderpivoted at its bottom to the outer end of the lower arm, a transverserod fixed on top of the pressure plate at its outer end and projectingoutwardly at the side edges of the pressure plate No references cited.
